I need to run ghc 5.02 or later on Solaris 2.6. I don't have any version of ghc on the machine. Are there binaries for 2.6 still? Alternatively, is it possible to build it without ghc?

You might find that the 2.7 binaries work on your system. Failing that, you'll need to bootstrap GHC from .hc files, starting from version 4.08.2. Instructions are here: http://www.haskell.org/ghc/docs/latest/html/building/sec-porting-ghc.htm l Cheers, Simon
